About this world
TOI-2338 b is a gas giant orbiting TOI-2338, a yellow, Sun-like star 1.02 thousand light-years from Earth. It is about 1 times the size of Jupiter and holds 6 Jupiter masses. It completes an orbit every 22.7 days at 0.16 AU from its star, closer than Mercury is to the Sun, on a strongly elongated orbit (e = 0.68).
Its equilibrium temperature is about 799 K (526 °C): far too hot for liquid water on its surface. At its size it almost certainly keeps a deep envelope of hydrogen and helium.
It was discovered in 2023 by transit with Transiting Exoplanet Survey Satellite (TESS). A planet crosses its star and dims it by a tiny, periodic fraction.
